We report on the realization of a mixture of fermionic $^{161}$Dy andfermionic $^{40}$K where both species are deep in the quantum-degenerateregime. Both components are spin-polarized in their absolute ground states, andthe low temperatures are achieved by means of evaporative cooling of thedipolar dysprosium atoms together with sympathetic cooling of the potassiumatoms. We describe the trapping and cooling methods, in particular the finalevaporation stage, which leads to Fermi degeneracy of both species. Analyzingcross-species thermalization we obtain an estimate of the magnitude of theinter-species $s$-wave scattering length at low magnetic field. We demonstratemagnetic levitation of the mixture as a tool to ensure spatial overlap of thetwo components. The properties of the Dy-K mixture make it a very promisingcandidate to explore the physics of strongly interacting mass-imbalancedFermi-Fermi mixtures.
